Inductance Converter
Convert inductance between henries, millihenries, microhenries and CGS units.
Change the values and press Calculate to work out your own figures.
Enter an inductance, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

- 1 µH = 0.001 mH
- 470 × 0.001 = 0.47 mH
How to use it
Type an inductance, choose the unit it is in and the unit you want, then press Calculate. You can type decimals, fractions such as 3/8, mixed numbers such as 1 1/2, very large or small numbers such as 2.5e6, and simple sums such as 2*3. Swap exchanges the two units.
The answer is worked out with exact fractions and only rounded for display, to 12 significant figures. Below it you get the same value in every other unit on the list, and Show the working gives the factor that was used.
Key definitions
1 H = 1 V·s/A = 1,000 mH = 1,000,000 µH
Where you meet inductance
Coils, chokes and transformers are rated in henries. Small inductors on circuit boards are usually a few microhenries to a few millihenries.
Questions
How many microhenries are in a millihenry?
1,000.
What is an abhenry?
The CGS electromagnetic unit of inductance, one billionth of a henry.
Formulas
result = (value × f(from) + o(from) − o(to)) ÷ f(to)
